glusterd: support for tier volumes 'detach start' and 'detach commit'
Back port of http://review.gluster.org/10108
These commands work in a manner analagous to rebalancing when removing a
brick. The existing migration daemon detects "detach start" and switches
to moving data off the hot tier. While in this state all lookups are
directed to the cold tier.
gluster v detach-tier <vol> start
gluster v detach-tier <vol> commit
The status and stop cli commands shall be submitted separately.
